CAR-DOOR.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed December '7, 1905. Serial No, 290,808.

Be it known that I, MARION H. STICKNEY, a citizen of the United States,residing at in thecounty of Jackson and State of Missouri, have inventednew and useful Improvements in Car-Doors, of which the following is aspecification.

My invention relates to improvements in car doors. r

It relates particularly to improvements in doors of cars employed forcarrying grain or the like.

The object of my invention is to provide a car door that may be quicklyopened for permitting the grain or like material lying against the doorto fall out of the car and hasten the unloading of the car.

My invention provides a vertically movable inner door for closing thelower end of the usual side opening of the car, the door being pivotedto the car body at its upper l end so that the lower end of the door maybe swung outwardly and thus against the door to fall out.

My invention provides further releasable means for locking the graindoor against outward or upward movement after it has been closed.

It provides further means by which the door may be releasably retainedin the elevated position during the unloading of the car.

The invention provides further an inner outwardly swinging andvertically' movable inner door which in the closed position lies whollyupon the inner side of the path of movement of the usual outer door, sothat the outer door may be freely opened or closed.

My invention provides also novel means for sealing the side edges of thedoor against the entrance of grain between the car body permit the grainand the inner grain door.

Othernovel features are hereinafter fully described and claimed.

In the accompanying drawings illustrative of my invention. Figure 1 isan outer side elevation of a portion of a car provided with a grain doorof 'my invention, the door being shown in the lower closed position, aportion of the car body being broken away to show the mechanism on thecar body engaging one of the locking bolts. y Fig. 2 is a horizontalsectional view taken on the dotted line a-t of Fig. 1. Fig. 3 is asectional view taken on the dotted line c-d of Fig. 4.

Fig. 4 is a vertical sectional view taken on a lane corres onding inposition to the dotted ine c--f of ig. 1, the grain door being shownswung outwardly. Fig. 5 is a vertical sectional v'iew taken on thedotted line g-h of Fig. 4 looking outward as denoted by the arrow, thegrain door in this view being shown closed. Fig. 6 is a horizontalsectional view taken on the dotted line i-y' of Fig. 1. Fig. 7 is across section taken on the dotted line c-l of Fig. 3, the car rafterbeing shown in dotted lines.

Similar characters of reference denote similar parts.

1 denotes the body of an ordinary boX car employed for carrying grainand the like and provided in its side with the usual door opening 2.

3 denotes two vertical posts disposed one at each side of the opening 2,and forming a part of the car body.

4 is the ordinary outer car door,'shown in Fig. 2 and slidably mountedin the ordinary manner upon the outer side ofthe car to and from aposition closing the opening 2.

5 is the grain or inner door, vertically movable in the opening 2 andadapted to close the lower end of said opening; said door when in theclosed position, as vshown in Fig. 2, lies Wholly at the inner side ofthe path of movement of the door 4, thus permitting the door 4 to beopened or closed without striking the door 5. The upper end of the door5 is provided with laterally projecting trunnions 6, vertically slidablerespectively in two guides 7 comprising preferably two channel ironssecured respectively upon the sides of the posts 3 opposite the opening2 and having their upper ends extending upwardly and laterally andsecured to two rafters 8 of the car roof, denoted by 9. By

placing the channel bars 7 on the sides of the posts 3 opposite theopening 2 said bars do not obstruct the opening and are, furthermore solocated as not to be easily injured or to occupy valuable space in thecar. The trunnions 6 are preferably formed in the following describedmannerz-A horizontal bar 10 is secured to the inner side and upper endof the door 5. The ends of the said bar, adjacent to the side edges ofthe said door, are inwardly bent and extend transversely past the posts3 respectively, the eXtreme ends of said bar being formed into returnbends and mounted respectively in the guides 7. The guides 7 are. closedat their lower ends, as

shown in Fig. 4 and Fig. 5, thus forming supports upon which thetrunnions 6 are pivotally mounted, when the door 5 is in the lowerposition. When in this position the door 5 may be swung outwardly to theposition shown in Fig. 4, so as to permit the grain lying againstthedoor 5 to fall out of the car, thus facilitating the unloading of thecar.

For locking the door in the closed position, as shown in Figs. 1, 2 and5, the following described mechanism is provided:-Slidably mounted uponthe outer side of the door 5, are two horizontal bolts 11, mountedrespectively at their outer ends in two guides 12, secured to the outerside of the door 5 adjacent its side edges. The adjacent ends of thebolts 11 are pivoted respectively to a lever 13, at opposite sidesrespectively, of a bolt 14, secured to the door 5 and upon which thelever 13 may be oscillated. By oscillating the lever bolts 11 may beforced in and out of two recesses provided one in each post 3 adjacentthe door 5. To lock the lever 13 against movement when the bolts 11 arein the locked position, the said lever is provided with a slot 15,adapted to receive a staple 16, secured to the outer side of the door 5and adapted to receive a pin 17, which rests upon the outer side of thelever 13, as shown in Fig. 1. To retain the door 5 in the elevatedposition, as represented in Fig. 3, two bolts 13 are securedtransversely in the rafters 8 respectively and have mounted on theirinner ends respectively, two hooks 19, adapted, when the door 5 is movedin its most elevated position, to enter the notches 20 provided one eachin the lower end and inner side of an inwardly extending flange of avertical angle iron 21 secured to the outer side and adjacent edge ofthe door 5. The inwardly extending flanges of the angle irons 21 areslidably mounted respectively between the posts 3 and the outwardlyextending flanges of two vertical angle irons 22, secured upon the innersides respectively of the posts 3. The overlapping angle irons 21 and22, seal the said vertical edges of the door 5 against the admission ofgrain between the posts 3 and the door 5.

In operating my invention the door 5 is swung to the lower positionshown in Figs. 1 and 5, after which the lever 13 is swung to theposition shown in solid lines in Fig. 1, thus forcing the bolts 1 1 intothe recesses provided in the posts 3, thus locking the door 5 againstoutward or upward movement. The car may now be loaded with grain. lVhenit is desired to unload the car the pin or other securing device 17 isremoved from the staple 16 and the lever 13 sprung outwardly from thestaple and swung to the position indicated in dotted lines in Fig. 1,after which the door 5 will be swung outward by the weight of the grainto the position shown in Fig. 4. After the grain adjacent the door 5 hasfallen out, the door 5 is moved upwardly on its trunnions 6, moving inthe guides 7 until the notches 20 are disposed opposite the hooks 1S),at which time the lower end of the door is allowed to swing downward tothe position shown in Fig. 3, with the hooks 19 resting in the notches20. To close the door it is but necessary to raise the lower end thereofso as to release it from the hooks 19, after which it may be lowered tothe position shown in Fig. 1 and locked in such position, in the manneralready described. It will be understood of course, that prior tounlocking the door 5 the door 4 is first moved laterally to a positionclearing the opening 2.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:-

rllhe combination with the car body having a side door opening and twovertical posts at opposite sides of said opening, of two angle ironssecured respectively to said posts and having outwardly extendingflanges, two channel bars having vertical portions secured respectivelyto said posts and having their upper ends extending inwardly andupwardly, the channel sides of the bars being the sides distant fromsaid opening, a door for closing said opening, a horizontal bar securedto the upper end of said door and having return bends at its endsslidably and pivotally mounted in the channels of said channel barsrespectively, vertical angle bars secured respectively to oppositevertical edges of said door and having inwardly cxtending fiangesdisposed respectively between said posts and said outwardly extendingflanges, said inwardly extending ianges having notches adjacent theirlower ends, hooks pivoted to the roof of the car body and adapted whenthe door is raised to enter said notches to retain the door in the openposition, and releasable means for locking the door in a positionclosing said opening.

In testimony whereof l. aflix my signature, in presence of twosubscribing witnesses.

MARION H. STICKNEY.
